Chlorine is in drinking water to make it safe, but it’s highly toxic to fish: leave the tap water standing in a clean container for at least 24 hours before use. other methods can be used to de-chlorinate water; your local aquarium can help with this.

Ordinary tap water is fine for filling up the aquarium as long as you let it sit for several days before adding fish (the chlorine in the tap water will kill the fish). It is a good idea to let the filter run for a week before adding fish to the tank.

Tap water requires not less than 24 hours to dechlorinate. In some cases, it can even take up to 5 days for the chlorine to evaporate from your water fully.

Tap water contains very small amounts of chlorine that we use to remove harmful bacteria. Although chlorine is completely safe for us, it can be very dangerous to fish. using a fine spray when filling up a pond – this will aerate the water and remove the chlorine.

Any dead fish should be removed, as its body will quickly rot in the warm, bacteria-laden water. A corpse will pollute water, risking the health of other fish in the tank. If it died from disease the last thing you want is other fish consuming its body parts, so remove immediately.

Hold your fish upright and place the outflow of water right at the fishes mouth, or if the fish is big enough, put the line directly in its mouth. Do this for 20-30 seconds at a time giving maybe 1-3 minute breaks in between.

Strange Swimming: When fish are stressed, they often develop odd swimming patterns. If your fish is swimming frantically without going anywhere, crashing at the bottom of his tank, rubbing himself on gravel or rocks, or locking his fins at his side, he may be experiencing significant stress.

On the other hand, if your tank’s pH is (for example) 6.3, while your replacement water has a pH of 7.5, replacing 50% of the water all at once will change the pH of your tank significantly (possibly more than 50% depending on buffering factors), which will stress your fish, possibly enough to kill them.

Short answer is yes, you can over condition your water. Longer answer is that it’s really hard to do. Unless you dump an entire bottle of conditioner in your tank, your fish will be fine. Conditioner essentially removes the harmful effects of chlorine and chloramines from your every day tap water to be safe for fish.
